Hi.I'm not sure if this is the right place to post this, but I couldn't find any other forum that fits better.If this is the wrong place to post feel free to move my post to the proper location.If you don't offer this type of help, can you please point me in the right direction?

I need help configuring my Cisco 877 ADSL router. I've tried reading guides and such but I just don't get it to work. Current config is set up via SDM (and doesn't work).What I need is a simple config which gives all machines on the lan (192.168.0.x) internet access. I've found lots of PPPoA configs but my ISP (Telia Sweden) doesn't use that. They use enet encap.There is no login or password needed for my internet access. My other linksys router is configured as follows:

I don't need any unneccesary services at all. As long as I get a basic running config I can experiment with it myself and just revert if I mess things up. This way I can start learning configuring the device via the console.

Please comment as much as possible so that I know what the config does.

My current messy config:(Feel free to comment, cut, paste, add whatever you want. Since I don't understand much of the config. I see that i have two ATM interfaces, I don't know why, feel free to remove one if it's not needed.)

I think I know what you are talking about as some of my remote branches in Scandi use 877 Routers. 877 config is different in all three countries (Denmark, Sweden and Norway) but as you asked, I am pasting my Swedish config below. Hopefully this would help you. I am not 100 % sure that my ISP is the same as yours but looks like I am using a similar config which doesn't require a password etc.

Please note in Sweden you need to configure "interface ATM0.35 point-to-point" subinterface and you can't use the traditional Dialer interface. Also I have noticed that I get static IPs from ISP, but in your case you need to use the "dhcp" option as per the config below.

And I can also see that the current software installed on the router is C870-ADVSECURITYK9-M. I do not have Annex-M support on my connection. Will it work with Annex-A aswell or do I have to update the software on the router?
